        <div class="description">
            <p> This sample shows how to configure CKEditor to output valid
                <a class="samples" href="http://www.w3.org/TR/xhtml11/">XHTML 1.1</a> code. Deprecated elements (<code>&lt;font&gt;</code>, <code>&lt;u&gt;</code>) or attributes (<code>size</code>, <code>face</code>) will be replaced with XHTML compliant code. </p>
            <p> To add a CKEditor instance outputting valid XHTML code, load the editor using a standard JavaScript call and define CKEditor features to use the XHTML compliant elements and styles. </p>
            <p> A snippet of the configuration code can be seen below; check the source of this page for full definition: </p> <pre class="samples">
